CHARLES NEELY, OF EBENSBURG', PENNSYLVANIA.

SHINGLE-CUTTING DEVICE.

Application filed April 7, 1915.

To all whom it may concern:

Be it known that I, CHARL S NEELY, a citizen of the United States,residing at Ebensburg, in the county of Cambria and State ofPennsylvania, have invented certain new and useful Improvements inShingle-Cutting Devices, of which the following is a specification,reference being had to the accompanying drawings.

This invention relates to an improved shingle cutting device of thatcharacter shown and described in Patent No. 1,092,381, issued to meApril 7, 1914.

The present invention has for its primary object to generally simplifyand improve the construction of my original invention, whereby asbestosshingles may be expeditiously and accurately out without danger ofbreaking or mutilating the same so as to render them unfit for use.

It is a more specific object of my invention to provide an improvedconstruction and mounting of the movable knife blade whereby a shearingout upon the material at the necessary pressure may be obtained with aminimum of manual labor.

It is an additional object of the invention to produce a cutting devicefor asbestos shingles which is highly durable as well as very eliicientand reliable in practical operation and may be produced at comparativelysmall manufacturing cost.

With the above and other objects in View, my invention consists in thenovel features of construction, combination, and arrange ment of partsto be hereinafter more fully described, claimed, and illustrated in theaccompanying drawing, in which,

Figure 1 is a perspective view illustrating the preferred embodiment ofthe present invention Fig. 2 is a transverse section of the device; andFig. 3 is a section taken on the line 3-43 of Fig. 2.

Referring in detail to the drawing, 5 designates the base or body bar ofthe device, the opposite ends of which are boltcd or otherwise rigidlyfixed upon the blocks or cleats 6. Each of these end blocks is providedwith a standard consisting of the spaced vertical arms 7 between whichone end of the vertically movable cutter bar 8 is engaged. Upon one faceof this bar, the longitudinally extending cutting blade 9 is secured bya series of screws indicated at 10. This cutting blade tapers 1on-Specification of Letters Patent.

gitudinally from one of its ends to the other and the cutting edgethereof, indicated at 11, is disposed below the plane of the lower edgeof the bar 8. This cutting edge of the blade 9 is very slightly inclinedor beveled transversely, and it is in this slight inclination of thecutting edge of the blade that the practical effectiveness of thecutting action resides. To the opposed longitudinal edge of the base orbody bar 5, a metal strip 12 is secured, with the upper edge of whichthe cutting edge 11 of the blade 9 co-acts.

' To the opposite ends of the vertically movable bar 8 and upon theupper edge thereof, the lugs or ears 13 are secured. lever 14 isfulcrumed at one of its ends upon a transverse bolt 15 which is mountedin the upper ends of the spaced vertical arms 7 on one of the end blocks6. The other end of this lever 1 1 is provided with a longitudinallyextending slot 16. A relatively long lever 17 is fulcrumed at one endupon a bolt 18 secured in the upper ends of the arms 7 on the other ofthe end blocks 6. This latter lever, intermediate of its ends, carries abolt 19, preferably provided with an anti fric-- tion roller which isslidably engaged in the slot 16 of the lever 14. Spaced links 20 connecteach of the leverslt and 17 adjacent its pivoted end, to one of the ears18 on the cutter bar. A rubber cushioning disk, inclic'ated at 15, forthe lever 17 is arranged upon the end of the bolt 15.

It is to be particularly observed, from ref erence to Fig. 2 of thedrawing, that the cutting edge 11 of the knife blade 9 is slightlyspaced laterally from the edge of the metal strip 12 which is secured tothe base 5 so that they will not contact with each other in theoperationof the device.

In the operation of the machine, the asbestos composition shingle islaid. upon the base 5, the asbestos sheet projecting over the upper edgeof the plate 12 and beneath'the cutting edge of the blade 9. Theoperator now forces downwardly upon the free end git,

downward pressure, there will be a shearing cutting action of the knifeblade through the sheet of asbestos.

The base 5 of the device is provided with a suitable gage indicatedgenerally by the numeral 21. As this gage is fully shown and describedin my prior patent, above referred to, the same will not, therefore, beset forth in detail in the present specification. It will sufiice tostate that, by simply adjusting the movable gage bar to the properposition, shingles of any desired dimensions may be quickly andaccurately out.

From the foregoing description, taken in connection with theaccompanying drawing, the construction, manner of operation, and severaladvantages of my invention will be apparent. It will be seen that l havematerially simplified and improved the construction of my priorinvention, whereby the same is rendered more positive and reliable inits action, T he device may be operated with a minimum of labor upon thepart of the operator to quickly cut a large number of shingles. lit isapparent, of course, that the body bar which carries the movable cuttingblade may be of any desired cross-sectional form as may be requisite inorder that the same will have the necessary inherent strength. In viewof the fact that the device embodies in its construction but few partswhich are all of exceedingly simple form, it will further be seen thatthe invention can be manufactured and sold at relatively small cost.

While I have shown and described the preferred construction andarrangement of the several elements, it is to be understood that thedevice is susceptible of considerable modification therein, and I,therefore, reserve the privilege of resorting to all such legitimatemodifications as may be fairly embodied within the spirit and scope ofthe invention as claimed.

' Having thus fully described my invention, what I desire to claim andsecure by Letters Patent is l. in a cutting device of the characterdescribed, a vertically movable cutter bar, guides for the ends of saidcutter bar, levers pivotally mounted at one of their ends upon saidguides and connected to each other for relative movement, one of saidlevers being provided with a handle, and links connected to therespective levers contiguous to their pivoted ends and to the relativelyopposite ends of the cutter bar.

2. A cutting device of the character described including a verticallymovable cutter bar, guides for the ends of said cutter bar, leverspivotally mounted at one of t 'ieir ends upon the respective guides, oneof said levers being provided in its free end with a longi tudinal slot,a bolt fixed in the other lever for longitudinal movement in slot, saidlatter lever being provided with a handle, and links connected at one oftheir ends to the respective levers contiguous to their pivots and attheir other ends to the rela tively opposite ends of the cutter bar.

3. A cutting device for asbestos shingles incli'lding a base, a metalplate secured t: one of the longitudinal edges of said base, avertically movable cutter bar, guides upon the base in which the ends ofthe cutter bar are movably mounted, a cutting blade fixed to one face ofsaid bar and having its cutting edge disposed. below the plane of thelower face of said bar, the cutting edge of said blade beinglongitudinally inclined with respect to the base to effect a shearingcut, and manually operable means connected to the cutter bar to actuatethe same.

4. A device for cutting asbestos shingles includin a base, a metal platesecured to one of the longitudinal edges of said base, a verticallymovable cutter bar, guides on the base in which the ends of the cutterbar are engaged, a cutting blade secured upon one face of said bar andhaving its cutting edge slightly inclined transversely and disposed slowthe plane of the lower face of said bar, said cutting edge of the bladebeing longitudinally inclined with respect to the base to effect ashearing cut, and manually operable means mounted upon said guides andconnected to the cutter bar to actuate the same.

In testimony whereof I hereunto affix my signature in the presence oftwo witnesses.
